(Looking to purchase a dissertation you found at the AMS index of dissertations in musicology, DDM-Online? Many American dissertations are available through the facility provided by ProQuest: Dissertation Express. Some British doctoral theses are available through the British Library Document Supply Centre. If neither of these has what you seek, you should attempt to obtain a copy by contacting either the library of the institution which awarded the degree, or the author.)

(Looking for AMS Press? Sorry, that publisher is not associated with the American Musicological Society. Please see their web site.)
